Adolescence is one of the most exciting yet challenging periods in human development. Generally thought of as the period of life that occurs between 12 and 21 years of age, adolescence is a period of tremendous physiologic, psychologic, and cognitive transformation during which a child becomes a young adult. The gradual growth pattern that characterizes early childhood changes to one of rapid growth and development, affecting physical and psychosocial aspects of health. Changes in cognitive and emotional functioning allow teens to become more independent as they mature. Peer influence and acceptance may become more important than family values, creating period of conflict between teens and parents. Because all of these changes have a direct effect on the nutrient needs and dietary behaviors of adolescents, it is important that health care providers develop a full understanding of how these developmental changes of adolescence can affect nutritional status.
